Here's the back story to this question: I got a two pack of steaks last night for last night's supper and today's lunch when I picked up that pork shoulder. Since I was totally wiped, I wanted to get them cooked with a minimum of fuss so I seasoned them up, seasoned the pork shoulder and put it in the fridge, then dropped a bunch of large lumps of charcoal in a chimney and got that started and cooked the steaks.
Normally, I try to break up the big lumps so they're in average sized chunks so that I have a even fuel density. The large lumps I used last night were all the ones I couldn't break apart by hand that I'd set aside over the last year. This was a mix of Royal Oak and Maple Leaf chunks. It took a while for them to start up and there was some hissing of escaping steam. I guess some of the older lumps that had been sitting for a year or so absorbed some moisture. Anyways, the steaks turned out well, which is why I'm questioning the need to break up the huge lumps. Should I worry less, fill my chimneys and let them go however they may or continue breaking down the huge lumps into average sized pieces? What do you guys do?
